PROCESS FOR THE TREATMENT OF IVIETALS AND ALLOYS. 1
No Drawing.
I To all whom it may concern:
Beit known that we, Geonou BRYANT, of 1? .Iilackstoelr road, l inslmry Park, in the county cf London. lug-land, and (Enhance .lzlouaer; .IYIXNUN, ot Wyngarth, Ualrfield toad, l llorrl. in the county of Essex, England, subjects of the King of England, have invcntrd a new and useful. Process for the Treatment of Metals and Alloys, of which the following is a specification.
i This invention relates to a process for the treatment of metals and alloys, including solders, which melt at a comparatively low temperature, with chemical reagents that will purify the same to some degree by cleaning them with fluxes to remove unclesirahh-i substances, such as silica, oxide of extraneous metals, etc. Such metals, moreover, mix and alloy readily with one another when in. a molten state. In the case of the solder oxidation is prevented so that perfect union ofthe solder with the metal or alloy to be joined is secured.
The process consists essentially in bringing the i'netals or alloys, while in a molten state and in a fine state of sub-division, into contact with'a flux or successively into contact With solvents containing the chemical reagents in a state of solution. After treatment the particles are removed and may he remelted {or use.
A preferred method consists in passing the molten metal through a sieve and allowing the minute drops to fall into the cleaning solution, or layers of solutions containing the chemical reagents which have a fluxing action that tend to remove impurities from the surfaces of the drops. The sieve or the like should be placed very near the surface of the liquid into which the minute drops are to fall, so that the metals may-be perfectly molten when reaching the liquid.
As suitable fluxes various mctallic salts may he used, such as chloride, cyan-ids,
' chrou'iates, ferro-cyanids, vanadates, molyhdates; or instead suitable acids and alkalis may be employed; Also sulfur, phosphorus,
' iodin, and similar elements dissolvedin oil,
fats, waxes, petroleum, turpentine, alcohol and water may be used as fluxes.
'lhe 'lollowingls an example of the treatlw-nt of one metal by the foregoing process:-Zinc is melted and then passed through a sieve to finelydivide the same, and these particles are then passed through Specification of Letters Patent.

two solutions, viz :an oil solutiono't' phosphorus, and 'a Water solution of Zinc ehlo rid or ammonium ehlo'i'id', the oil solution floating upon the surface of the water sol 1.1-" tion. The resulting granulated metal al loys practically instantaneously with molten copper producing brass alloys of regular composition, free from oxid and extremely tough. In the case of solder the SubStQD'i Q'. is melted and treated in like manner.
It would appear that the action which takes place is complex. Generally the reagent in the oil solution combines with the oxids on the metal or alloy treated and the product formed is removed by being dissolved in the water solution, the presence of dissolved fluxes in this solution facilitating the solution.
It will 'be understood that the chemical substances are chosen according to the nature of the metal and the impurities to. be removed. lVhere. two solutions are used We prefer to simplifythe process to have the so lutionS in layers in the same vessel, for instance we may have a' solution of chemical substances in oil, which latter solution is floated on top of the former so that the drops of molten metal pass through the fluxes in a particular order, as in the case of the example given above. In practice it is found convenient'in the example given to float the solution of phosphorus in oil upon the solution of zinc chlorid and Water, as this saves the necesisty of melting the'metal a second time.
What is claimed is 1. The process of treating metals which consistsin melting said metals, and passing the same successively through a plurality of layers of different. solutions containing suitable fluxes for the purpose of cleaning the same.
2. PlIB PI'OCP/SS of treating metals and ren- (lo-ring them more easy to alloy with other metals which consists in meltingsaid first mentioned metals; in finely dividing the same; and in causing the finely divided molten metals to be subjected to solutions containing reagents capableof chemicallyeleaning the surfaces of the metals.
3. The process of treat1ng a metal and rendering the same more easy to alloy, which,
consists-in finely dividing said metal while H! a molten OOINlItlQH; and In immed ately passing thesame through successlve layers lnctahsubstantially as described.
of oil. and water containing a chemical capable of cleaning the surfaces of the metal particles.
4.. The process of treating a metal and rendering the same more easy to alloy, which consists in finely dividing said metal while in a molten condition; and in immediately passing the same through successive layers of oil containing a reagent capable of changing the oxid coated globules of the metal, and of water containing a chemical capable, of exerting a cleaning action upon said The process of: treatlng metals to be used as solders which consists in melting such metals, finely dividing the same, and
bringing the finely divided particles into inmetals while in a molten and finely divided state into intimate contact with an oil solution and a water solution of a chemical compound, said oil solution containing a solute diflerent from the solute in the water solution, substantially as described. I
In testimony whereof, we affix our signatures, in presence of two witnesses.
